Most of the cars on this site have been modified for performance applications and i would assume that these would not be eligible for your event - do correct me if this is not accurate.
On the flip side, there are a few well kept survivors and restored Datsun 510, Z car and roadster models here.

Welcome, and we'll spread the work. I'll also add this event to our calendar.

Hi James - precisely one of the few original cars. I think Maurice V 510, Sahib 510, John V's roaster, the 1200 on the Island, and a small handful of other classic Datsun's locally are the showcase cars that would fit this pre-73 bill.
